Living in the Orlando area too I read it. They won't be happy till they make ALL the water Manatee zones.
I recently went up the St. Johns River. What a joke. If you start at Sanford and head north. It is either "No Wake" or "25 MPH Maximum Speed". Heck I got told I was going too fast. I was in my 1949 Chris-Craft.
Also, the river is dead, very few boats. Above Deland heading toward Lake George it is better in many spots.
A real shame.
